Add/edit features while recording GPX track

Bug report about editing a way while recording a gps track:

> Was walking with recording a gps track, while attempting to edit a way. While I was in the Edit Way the app said my track was still recording, but I walked several hundred more meters on this screen and the gpx track was actually not being recorded when I was finished.

It would be pretty cool if adding/editing features was possible while separately recording the gps track, and I think is reasonable expected behavior.
